Inventor: DOUMAUX ARTHUR ROY JR
IPC: C07C201/04
Filed: 1982-01-22
Abstract: The invention deals with the preparation of methyl or ethyl nitrite from the corresponding alcohols in a vapor phase process. 
     A molar amount of nitrogen oxide composition containing a nitric oxide to nitrogen dioxide molar ratio of greater than 1 is reacted in a vapor state in a reactor (76) with a molar amount of vaporized methanol or ethanol wherein the molar ratio of methanol or ethanol to the combined molar amount of nitric oxide and nitrogen dioxide is greater than 1, at a temperature of 10°C to 300°C in the presence of an inert gaseous diluent. 
     This process may be run at relatively low temperature and pressure while minimizing the formation of by-products.

Abstract: The system comprises main intake lines (2) and auxiliary intake lines (7) which in each case have a common inlet (5, 8), a throttle (4, 9) being arranged in each inlet (5, 8). The main intake lines (2) are controlled by inlet valves (6) of the internal combustion engine (10). The auxiliary intake lines (7) open into the main intake lines (2) close to the inlet valves (6). When the engine (10) is under low load, the inlet of the main intake lines (2) is largely throttled whilst the throttle (9) of the auxiliary intake lines (7) is load- dependently operated. A control device (11) is proposed which opens each auxiliary intake line (7) under cycling control or intermittently. This achieves a relatively low pressure level in the main intake lines (2) so that each cylinder (I, II, III, IV, V, VI) receives its filling in the intake cycle via a free charging jet of considerable mass and high velocity from the associated auxiliary intake line (7). <IMAGE>

Abstract: a A belt conveyor (12) and a conyeying system (10) using a belt conveyor (12). The system is designed to convey articles around curves and between vertically and horizontally spaced locations. The belt (12) used in the system has a central substantially inextensible flexible spine (20) and an upper load carrying portion (22) supported by the spine (20). The load carrying portion (22) has a plurality of ribs (40) and a plurality of pleats (42) interposed between the ribs (40). The ribs (40) provide rigidity for the belt and limit movement of articles with respect to the belt, while the pleats (42) provide longitudinal extension and contraction of side edges when the belt is following a curved path. The distance between top edges of the pleats (42) and top edges of the ribs (40) increases from outer edges of the belt towards the center so that top edges of the pleats (42) have a generally V shape and conveyed articles and juices and liquids exuded from the conveyed articles tend to be conveyed in a central region of the belt.

Abstract: A fiber optic probe (8) to be implanted in human body tissue for physiologic studies involving measurement and monitoring of the partial pressure of gaseous oxygen in the blood stream, which is coursing through a particular blood vessel in the body. The use of the probe (8) is based on the principle of dye fluorescence oxygen quenching. Structurally the probe (8) comprises two 150-micrometer strands of plastic optical fiber (12,14) ending in a section of porous polymer tubing (10) serving as a jacket or envelope for the fibers. The tubing (10) is packed with a suitable fluorescent light-excitable dye (15) placed on a porous adsorptive particulate polymeric support (16). The tubing or jacket (10) is usually made of a hydrophobic, gas-permeable commercial material, known as Celgard, but other suitable hydrophobic gas-permeable material could be used for such structure. The fiber optic probe (8) is of very small size and flexible so that it can easily be threaded through small blood vessels which are located in a variety of tissues of the body.

Abstract: Pairs of tights are transferred one pair at a time from a knitting machine to another machine, firstly by drawing the feet into two suction tubes axially in line so that they are stretched apart. As they are released from the discharge elements of the knitting machine, two arms are rotated so that they are swung together to fit into an opening left between the seams so that they can be passed to a transfer device. The two arms, which are triangular, have their tips bent over, and when swing open again, stretch the opening so that it fits over a ring of pins on the transfer device. These pins are expanded, and the two arms are rotated axially for disengagement, after which they can be swung apart again.
